Electronic voting systems have the potential to improve traditional voting procedures by providing added convenience and flexibility to the voter. Numerous electronic voting schemes have been proposed in the past, but most of them have failed to provide voter authentication in an efficient and transparent way. On the other hand, GSM (Global System for Mobile communications) is the most widely u...

Positioning technologies that use Global System for Mobile Communication (GSM) networks for location estimation (such as the Privacy Observant Location System (POLS) and the Place Lab framework) lack the accuracy that other positioning technologies like the Global Positioning System (GPS) have. GPS receivers are capable most of the time of placing a person within 10 metres of a known location. ...

objective: electro-magnetic radiation (emr) is emitted from mobile phones. various researches have shown relationships between mobile phone emr exposure to cancer and neurologic damages. this study aims to investigate the effects of mobile phone emr on brain antioxidant enzyme activity and the learning process. methods: rat pups and their dames were exposed to emr for 3 h per day from p2 to p1...

Ejaculated, density purified, human spermatozoa were exposed to pulsed 900 MHz GSM mobile phone radiation at two specific absorption rate levels (SAR 2.0 and 5.7 W/kg) and compared with controls over time. Change in sperm mitochondrial membrane potential was analysed using flow cytometry. Sperm motility was determined by computer assisted sperm analysis (CASA). There was no effect of pulsed 900...

OBJECTIVE It has been reported that GSM electromagnetic fields (GSM-EMFs) of mobile phones modulate--after a prolonged exposure--inter-hemispheric synchronization of temporal and frontal resting electroencephalographic (EEG) rhythms in normal young subjects [Vecchio et al., 2007]. Here we tested the hypothesis that this effect can vary on physiological aging as a sign of changes in the function...

In current electronic commerce systems, customers have an on-line interaction with merchants via a browser on their personal computer. Also payment is done electronically via the Internet, mostly with a credit card. In parallel to this, e-services via wireless-only systems are emerging. This paper identifies security and functionality weaknesses in both of these current approaches. The paper di...

A modern world contains varieties of electronic equipment and systems like: TV, security system, Hi-fi equipment, central heating systems, fire alarm systems, security alarm systems, lighting systems, SET Top Box, AC (Air Conditioner) etc., we need to handle, ON/OFF or monitor these electrical devices remotely or to communicate with these but, if you are not at the home or that place and you wa...

Recent studies have indicated that acute exposure to low level radiofrequency (RF) electromagnetic fields generated by mobile phones affects human cognition. However, the relatively small samples used, in addition to methodological problems, make the outcomes of these studies difficult to interpret. In our study we tested a large sample of volunteers (168) using a series of cognitive tasks appa...

Transtelephonic electrocardiographic transmission (TET) is the most widespread form of telecardiology since it enables clinicians to assess patients at a distance. The purpose of this study was to assess the efficacy and effectiveness of TET either by fixed telephone line (POTS) or by mobile phone in the preparticipation screening of young athletes. A total of 506 players, aged 20.5 +/- 6.2 yea...
